The synthesis of imines and enamines typically occurs under mildly acidic conditions, yet the reaction that you will perform in this experiment is successful without the need of such acid. Why?
If the 300MHz 1H NMR spectrum of a compound has a doublet with one signal at 6.10ppm and the second signal at 6.05 ppm, the value of the coupling constant is?
What is the purpose of the sodium carbonate in Part A. Why do we add glacial acetic acid in Part 1B when we react N,N-dimethylaniline, but we don;t use it with the other aromatic couplings reagents
A well-insulated rigid tank of volume 0.2 m3 initially contains helium at 70°C and 200 kPa. A valve connected to the tank is opened, and helium is withdrawn slowly until the pressure within the tank drops to p. An electrical resistor inside the ta..
Calculate the mass of aluminum deposited on the purified aluminum metal by the application of a current of 1.225 kiloamperes for 30 minutes from a very large quantity of a solution containing Al3+ ion in the Al2O3/Na3AlF6 molten state.

When atomic absorption spectrophotometer had been allowed to adequately equilibrate, a blank determination of absorbance gave the following results.
At equilibrium, the flask contains 90.6g HI Calculate the equilibrium constant for the reaction at this temperature.
The commercial synthesis of adipic acid involves the oxidation of cyclohexanol with nitric acid. List the hazards involved with this process, and briefly comment on both the environmental impact and personal exposure issues associated with the com..
Constant-boiling HCl can be used as a primary standard for acid-base titrations. A 50.00 mL sample of constant-boiling HCl with a concentration of 0.1193 M was collected and titrated to an end point with 34.89 mL of Ba(OH)2 solution. What is the m..
Draw the skeletal structure of the major organic product in the following reaction (water is also a product).
The Greek mathematician Archimedes is credited with discovering how to verify the amount of pure gold in an irregularly shaped object (e.g., a crown) by placing it in water.
